Abstract:
Objective: To determine the content of baicalin in Shuanghuanglian Injection. Methods: Baicalin was separated from injection by the precipitation separation with chlorhydric acid and determinel by UV spectrophotometry. Results: The average content was 6～9mg/ml, RSD was 0.34%. This result was similar to the results obtained by HPLC. Conclusion: This method is simple, highly sensitive, reproducible with stable results. It can be used as a quickly quantitative method for the quality control of this injection.
